GQMBINEI) SAFETY-PIN AND CLASP.

Specification of Letters Patent.

Patented May 18, 1920.

Application filed November 19, 1919. Serial No. 339,182.

To all whom it may concern:

Be it known that I, CARL FISHER, a citizen of Germany, and residing atBridgeport, in the county of Fairfield and State of Connecticut, haveinvented new and useful Improvements in Combined Safety-Pins and Clasps,of which the following is a specification.

My invention relates to a combined safetypin and clasp, made of a singlelength of resilient wire and embodying a point and a keeper therefor,the device being so constructed as to admit of the disengagement orrelease of the pointwith its keeper by a mere relative movement of theback of the pin, accom lished in such manner that the point is held inproper position to pierce the article or fabric to which the pin is tobe attached. Another object is the provision of a device of the abovecharacter which is very simple as well as strong and durable inconstruction, which may be manufactured at small cost and which ishighly convenient and serviceable in practical use.

A still further object is the provision of certain improvements in thecombined safet -pin and clasp disclosed in my United btates LettersPatent No. 1,192,613, granted July 25, 1916. I

For a full understanding of the invention,

reference is to be had to the following description and accompanyingdrawing, forming a part of this specification, and in which Figure 1 isa side elevational view of a combined safety-pin and clasp made inaccordance with my invention.

Fig. 2 is an enlarged section, taken on the line 2-2 of Fig. 1. v

Figs. 3 and l illustrate the use of my device as a watch guard andneck-tie clasp, respectively.

11 s clearly illustrated in the accompanying drawing, the device is madeof a single strand of resilient wire, substantially of the samecross-section throughout, except as hereinafter stated, and is formedwith a straight back portion 5, bent or doubled upon itself at 6 toprovide a hook portion 7, which inclines outwardly with respect to theback portion, and which is tapered to a sharp piercing point 8.

At its opposite end, he back is bent or doubled upon itself at 9, thecurve being larger than that at 6, and thence it proceeds toward thepoint in a parabolic line 10, the

returning or incoming line on its outer side being recessedlongitudinally at 11 to receive the point 8 and to form a keepertherefor. Continuing from this recess, the wire is gathered into astrong spiral heap 12, slidably pressing on the side of the back 5 andpartly projecting into a plane above the back as shown. The provision ofthe outwardly inclined hook 7, taken in connection with the parabolicline and the spiral heap, affords a firm foundation for an effectiveclasping or shutting engagement between the piercin point and itsrecessed region or keeper. Mbreover, the strong spiral heap, which, aswill be understood from an inspection of Fig. 1, has an outward bend inorder slidably to engage the side of the back, is relatively yieldableoutwardly so as to permit an article to be passed between itself and theback, Owing to the resiliency of the material of which the device ismade, the back may be readily pressed toward the parabolic line,disengaging the point from its keeper in an obvious manner and bringingthe point into position either to pierce a bit of fabric or to have anarticle slipped upon the hook, for instance, the loop 13 of the watch14. As soon as pressure is removed from the back, the point isautomatically reseated in its recess. The loop engaged on the hook isthen slipped between the spiral heap and the back and thence upon theparabolic portion.

Fig. 4 shows my device attached to necktie 15. WVhen the hook has beenopened, as above described, the point is pierced through the fabric, andthen the pin is advanced, with the hook underneath and the spiral heapon top, until as much of the fabric as desired is engaged, whereupon thepoint is repierced through the fabric and engaged with its keeper. Thebit of'engaged fabric may be permitted to rest on the back, or the pinmay be swung around until the same rests on the parabolic portion asshown in Fig. 4. The illustrations show only two of the preferred usesof my device, and many other equally advantageous uses will readilysuggest themselves.

Having thus described my invention, what I claim is 2- 1. A combinedsafety-pin and clasp made of a single strand of resilient wire having astraight back portion, a hook outwardly inclined with respect theretoand terminating in a piercing point, a parabolic portion in plan withsaid hook and recessed to form a keeper for said hook, said parabolicportion terminating in a firm spiral heap.

2. A combined safety-pin and clasp made of a single strand of resilientWire having a straight back portion and bent upon itself at one end toform a hook which inclines out- Wardly with respect to the back portionand which is tapered to a piercing point, the opposite end being alsobent upon itself in a larger curve than the hooked end and thenproceeding in a parabolic part in plan with the hook, said parabolicpart being longitudinally recessed adjacent the piercing point toreceive the same and to form a keeper for the hook and the sameterminating in a firm spiral heap which slidably engages the straightback and projects into a plane therebeyond.

In testimony whereof I have signed my name to this specification.

CARL FISHER.
